Described is an installation and a method to recover most of the energy in the water flowing out of a water tank, such as a closed marine facility, by combining different sizes of pumps and generators to recover energy from the wastewater in a marine facility where it is possible to optimize the energy recovery by also synchronizing the need for degassing/skimming of the water. This is to optimize the water flow so that it best fits the performance characteristics of the combination of pump and generator, while at the same time the water's CO2 and particle content meet the requirements of breeders and the authorities. This will provide large energy savings for the breeders. Recovered energy may be used locally in the operation of the facility or exported back to the power grid.

Described is a tank system for through flow and recycling solutions for breeding of marine species, which comprises means for sedimentation of particles such as faeces. In principle, the tank system establishes at least two water reservoirs, and the water velocity of flow through the tank is regulated so that the water in one section moves sufficiently slowly and in absence of marine organisms to obtain efficient sedimentation in this water reservoir. Further, fluid is transported between the two water reservoirs with the use of a device which at the same time exchanges gasses in the fluid.
